As last Update Alternate Access Mapping for Central Administration site, and set it to a user-friendly name, like http://centraladmin:11660 And execute the command SetSPN with the highest administrator privileges.

 



If you have other servers, put them in the list. Again, for Kerberos Authentication, do not forget to put your site in "local intranet site"..
